UTILIZATION OF CO2 IN SEMI-CONTINUOUS CULTIVATION OF Spirulina sp. AND Chlorella fusca AND EVALUATION OF BIOMASS COMPOSITION
Abstract Cultivation conditions and the process considerably influence the composition of microalgae. The objective of this study was to use CO2 as a carbon source in semi-continuous cultivation of Spirulina sp. LEB 18 and Chlorella fusca LEB 111 and to evaluate the influence of the renewal rate on...
